摘要： An additive for lubricating oil may include a phosphite ester compound (A) having a specific structure and a phosphite ester compound (B) having a specific structure, wherein the (A):(B) mass ratio of the phosphite ester compound (A) to the phosphite ester compound (B) is in a range of from 99:1 to 80:20. Such an additive may be provided to a lubricating oil, capable of imparting wear resistance and demulsibility with respect to a base oil for lubricating oil, and to impart durability even in the presence of water.

摘要： A lubricant base oil composed of an ester. The ester includes a component (A) derived from trimethylolpropane in a molar percentage Amol % of 25 to 42 mol %; components (B) derived from monovalent straight-chain saturated fatty acids each having a carbon number of 8 to 12 in a molar percentage Bmol % of 33 to 55 mol %: and a component (C) derived from adipic acid in a molar ratio Cmol % of 12 to 34 mol %. The components (B) include lauric acid in a molar percentage of 5 to 50 mol %, and (BCOOH+CCOOH)/AOH is 0.90 to 1.02. AOH represents a hydroxyl equivalent of the component (A), BCOOH represents a carboxyl group equivalent of the components (B); and CCOOH represents a carboxyl group equivalent of the component (C).

摘要： A lubricant base oil which contains an ester. The ester constituting the lubricant base oil includes: a component (A) derived from pentaerythritol in a molar percentage Amol % of 20 to 30 mol %; a component (B) derived from a straight-chain fatty acid having a carbon number of 14 to 22 in a molar percentage Bmol % of 55 to 79 mol %; and a component (C) derived from adipic acid in a molar percentage Cmol % of 1 to 15 mol %. A molar ratio (Cmol/Cmol) of the component (C) derived from adipic acid and the component (B) derived from the straight-chain fatty acid having a carbon number of 14 to 22 is 0.02 to 0.25, and the ester has a hydroxyl value of 10 to 100 mgKOH/g.
